ELECTRlG-LAMP HOLDER- Specification of Letters Patent.

Yatented. July 10, 1908.

Application filed May '2. 1903. Beriai No. 158,620.

To all whom it may concern:

Be it known that I; REUBEN B. BENJAMIN, a citizen of the United States, residing at (Jhicage, in the county of Cook and State of Illinois, have invented a. certain new and useful Im ,roveinent in Electric-Lamp Holders, of which the following is a. full, clear, concise, and exact description, reference being had to the accompanying drawings, forminp a, part of this specification.

My invention relates to improvements in clectrio lemp holders.

It has for its object to produce a device of this character which is simple in construe tion, nest in op nuance, and cheap of manufacture. The device has also been desi ned particularly for the purposes which wi l he iereincfter made ap arent.

In the drawings i lusty-sting the preferred" embodiment of my invention, Figure I is a perspective view of my invention. Fig. 2 is a. vertical sectional View. Fig. 3 is it view with the casing and bushing removed, there by disclosing more particularly the interior arrangement of the arts. Fig. 4 illustrates a modified form contect-piete. Fig. 5

- illustrates another form of my invention with the casing and bushings removed.

In thedrawin 's a suitable base i is shown, which is prefcralily circular and which hes a central projection 2 and a circular flange 3 at its edge. Upon said base are arranged onnulsr contact-plates 4, which are prefcrshl held in position by screws 5 pussin throng i said base and tl ircaded into inwardly-turned lugs 6, formed upon said contact-plate. The two cozitect-plctes are preferably formed in tegrnh and one supports 21. preferably threadod lamp-receiving shell 7, which has an out wardiy-turnml flange 8, which hours upon the inner side of said contact-plate and 1s preferably secured thereto by solder or other means. Connected with said. contectlate and proi'cmhl formed integral therewit i is a terminal or g inding post 8 for connecting said plate and one oi the supply-wires by means of thebinding-screw1).

Upon the central projection ol' the base jn'ol'oi'sllly seeurod at center-spring contact 10 for the lamp, which. is preferably hold in position by a screw I 1., threaded thereon and passing through said l'mso. Over the hose is arranged it prel m-silly somisphoricnl casing 12, which has its edges bearing upon said base and surrounds the parts above described as mounted u on said base. This casing is provided wit an aperture to permit the passage of the la1npha.se into the lm'np-rccciving shell and is insulated from said hunp-rccciving shell preferably by a bushing 13, which is threaded upon said shell and preferably solely supports the catsing in ppsrtion. The ism -recciving shell is preferaly arranged in suc 1 position that the opening in said casing will be arrsn ed at one side of the center thereof, and sai lamp-resolving shell is disposed in such manner as to support the lamp in an inclined positiiin to the base. This construction has particularly designed for support-it a single lamp. The form oflemp-helding evicejust set forthg's particularly sdepted to he attaehed' to an elevated support and arranged to project the lam upwardly in an inclined position, for the ower half of the device, winch is presented to View, has an exceptionallymeat appearance.

The SUPPIY'WIZOS for the contacts of the lamp-receiving device are passed throu 11 holes 15 in the base and one connected to t e binding-post carried by the contactlate so porting the lamp-receiving shell on the ct or to a binding-post 16, connected with the center contact. In this way said wires and their connections are thoroughly protccted from view.

Sometimes it may be desirable to have two lamps supported by the device instead of one, and for this purpose the device shown in Fig. 5 is designed. Therein a. circular base is cmployedmnd a casin of a. construction similar to that used in tile device previously described is also used.' The contactpletes for supporting the lamp-receiving cle vices have their inner ends suitably connect- .ed to the base and their outer ends joined and supported from said base by a, strip 19. Said strip is provided with a. suitable bindingscrew 2H for connecting with said contacts plctes one of the supply-wires. The center contests 21 for the lamps are adapted to be connected with the other supply-wire by u binding-post 22, provided with a bindingscrcw 23 As in the construction described in Figs. 1 and 2, the lamp-receiving devices are arranged in such a manner that the lamps will be supported at an inclined position to the base. The openingafor the passage of said lamps into said lamp-receiving'device .are located onl at one side of the center of the casing. 11 this way the appearance of 'the lower portion of the casing'is still preserved, and therefore this device may be used in the same manner as the one before described. In Fig. 4 is.shown a modification of the contact-plate used in Figs. 1 and 2. Instead of employing a separate ring, as shown in said figures, for supporti the outer end of the contact-plate of the amp-receiving shell a stri 24 1s provided for thatpurpose.

any changesimay be made in the details of construction and arrangement and combination of parts herein set-forth without in, departing from the spirit of my inany way vention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. in a socket for incandescent lamps, the combination with a suitable base, ofa substantiall hemispherical metallic casing mounte thereon, damp-contacts arrange within said casingand a lamp-receiver carried on said base at one side of the center of the base and exte at an angle to the base and adapted to ho d the lamp in an angular or inclined position and to project the same toward one edge of the base, said casing being rovided Wit an opening at one side thereo o posite thesaid receiver to accommoda'te t e lamp, the other side of said casing being continuous, whereby a socket is roduced which will securely and rigidly old the lam in the desired angular position, substantial as described. 2. Ina socketnfor incandescent lamps, the combination with a suitable base of a substantiall hemispherical metallic casing mounte and extending at an angle to the base and adapted-to hold the lamps in an angular or sincbned position and to project the same toward one ed e of the base, said cas' ein provided wit openings at one side is ereo opposite said receiversto accommodate the thereon, lamp-receivers carried on said base at one sideof the center of the base amps, the other side of said casing being ,continuous whereby a socket is which' will securely and rigidly lamps stantiall as described.

In wi ness whereof I have hereunto sub scribed my name in the presence .of two Witnesses.
